for what it worth, when i was taking concealed handgun course, i been told never do "warning shot" in the air (can kill bystander), never try to shot legs/arm/hands/etc (you will miss, even if you will not miss, it still often fatal, and if not fatal, often not enough to stop person with blood full of adrenaline). On top of it chance of hitting someone behind leg/arm is high. What been taught is to only use deadly force to stop imminent danger. And to stop someone means to shoot into center of the mass (so aiming at head is not advised too.) Now, how you decide if using deadly force is necessary - is totally different area from how to properly use deadly force to stop attacker when you already decided you have to do it.
